Transient Phenomena in Compressive Failure

Transient Phenomena

The SKA's design is driven by the needs of cutting-edge radio astronomy for sensitivity and spacial resolution. However its design is also driven by the desire to explore the transient radio Universe. In addition to pulsars, the SKA will be able to carry out high time resolution observations of several classes of known and predicted transient sources. Here we consider a selection of them, and d...

Transient Phenomena in Electromagnetic Forming Processes

The paper deals with finite element model for analysis of electromagnetic forming process of thin metallic sheets. The investigation starts with the FLUX simulation of transient electromagnetic field phenomena, continues with a transient structural analysis using ANSYS Structural under loads previously evaluated and ends with an ANSYS Multiphysics fully coupled analysis. The paper emphasizes th...

Novel Transient Phenomena in Heterojunction Bipolar Transistors

The interaction between transferred-electron effect and base widening under transient conditions in III-V heterojunction bipolar transistors is considered. Modification of the collector field profile with an n+ doping spike is shown to cause a time delay for the onset of Kirk effect creating conditions for the inception of charge instabilities. Numerical simulations suggest the possibility of s...

Transient Lunar Phenomena: Regularity and Reality

Transient lunar phenomena (TLPs) have been reported for centuries, but their nature is largely unsettled, and even their existence as a coherent phenomenon is still controversial. Nonetheless, a review of TLP data shows regularities in the observations; a key question is whether this structure is imposed by human observer effects, terrestrial atmospheric effects or processes tied to the lunar s...
